The correct answer is an adapter because it facilitates the connection between a socket and a ratchet when they have different drive sizes. An adapter is specifically designed for this purpose, enabling the use of sockets that may not match the drive size of the ratchet. It typically features one end that fits the ratchet and another end that accepts the socket, allowing for versatility in tool use.

Other options do have their specific functions but do not specifically address the need for different drive sizes. An extension is used to reach fasteners that are in difficult locations, essentially lengthening the reach of the ratchet with a socket attached, but it does not change the drive size compatibility. A reducer serves a similar function to an adapter but is often used to connect a larger socket to a smaller drive ratchet, providing a specific size reduction rather than acting as a general adapter. A connector is generally used to join two tool components together, but it does not specifically account for drive size variations.
